2015/11/02 (M) Driveway Joe

Linda was up at 5:45 AM and off to the bakery at 6:15.  I got up at 6:45 AM, got dressed, and went to the bus to turn on the block heater and Aqua-Hot engine pre-heat loop.  I then made coffee and had breakfast, after which I e-mailed Mike (W8XH) to let him know Joe would be here all day today.  I then reset the clocks in the two digital cameras.

Joe was at Chuck’s a little before 7 AM to change the engine oil and filter and figured it would take one hour.  I started the main engine in our bus at 7:45 AM to warm up the oil and make it easier to drain.  I let it run for 20 minutes on high idle, dropped it to low idle for a minute and shut it down.  The block will hold heat for quite a while.

Chuck texted me at 8:15 AM to let me know that Joe was on his way to our place and Joe called about five minutes later.  He was on our street but called because he wasn’t sure he was in the right place.  He pulled in to our first driveway entrance just before 9 and pulled his van up behind the bus.

I had dumped the air in the suspension yesterday when I put the coach up on stands so Joe had me start the engine and air up the suspension as a safety backup should one of the stands fail.  I raised it up off of all four stands and then set it back down but quit dumping the air as soon as it was on each stand.

The work for today was routine annual chassis and engine maintenance.  Joe needed to have diesel fuel on hand so I drove to the Shell station and bought four gallons.  While I was there I picked up a large coffee for him at the co-located Dunkin Donuts.

When I got back from my errand run Joe was already lubricating everything on the chassis and engine that had a grease fitting using the Mobil 1 synthetic grease I bought yesterday.  He was starting to generate messy trash so I fetched a large plastic trash bag.  He drained the engine oil, removed the old filter, filled the new filter with oil, and spun it on.  He then added six gallons of Chevron Delo 100 SAE 40 Heavy Duty Engine Oil that I bought on Saturday.  I added 2 to 3 more quarts from the reservoir to use up the oil that had been in there for a while.  I then refilled the reservoir as it is very handy for topping up the oil.

Joe removed and replaced both coolant filters while I fetched a bottle of Detroit Diesel PowerCool engine coolant.  He added coolant to the expansion reservoir while I watched the sight glass on the side of the tank and told him when to stop.  He then had me help him with the secondary fuel filter, which we pre-filled with diesel fuel.  Last, but not least, we replaced the filter element in the Racor fuel filter / water separator.  Joe installed the new filter element and gaskets and topped off the fuel in the housing before putting the cover back on.

I started the main engine and let it run for 30 seconds to circulate the oil, coolant, and fuel.  Joe added a little bit more oil to bring the level up to just over half way between the L and H marks on the dipstick.  This is where the engine likes to run and if I fill it to the H mark it will get rid of the extra oil on its own.

With the maintenance on the bus completed we transferred all of the old oil from the drain pan into the one gallon plastic jugs that had contained the new oil and put them back in the 3-jug cardboard boxes for convenient transport.  Our local O’Reilly’s Auto Parts store accepts waste oil and filters so I will take them there for disposal.  Although I had my own bus work to do I hung with Joe until he was done.  I stayed near the bus and trimmed trees when he did not me to assist with things.

Joe offered to come back next year to do our annual service and suggested that we take an extra day to replace as many grease fittings as possible either with better fittings or with small lines running back to one or more conveniently located manifolds.  The manifolds would have an input for grease and a valve for each line allowing most of the chassis and engine to be greased without getting under the bus.  I must say that I liked the sound of that.  It would be a nice upgrade to the bus and would make a good article for Bus Conversion Magazine.

I did NOT have Joe remove driver side front tire so I could get the splash guard off and inspect the area under the tray behind the driver’s seat.  I will have to deal with that on my own.  I also noticed that the fuel tank was down to 3/8ths so I will have to take the bus out and refuel it at some point and may have to turn off the Aqua-Hot and use the electric toe-kick heaters instead until I can refuel.

Keith called at 1 PM to let me know he would not make it out to mow the grass today.  He will be here tomorrow morning, probably for the last time this season.  Joe was packed up and on his way at 1:45 PM.  He was headed to Chicago where he has a house but has not been there in the last 18 months.

After Joe was done I went to Painter’s Supply and Equipment in Howell to buy POR-15 and the POR cleaner/degreaser.  POR is a brand but stands for “Paint Over Rust.”  It reacts chemically with rusted metal to stabilize the metal and prevent further rust.  I bought a can of spray on rubber material to put over it.  The POR-15 was pricey at $33 for a pint, but it is serious stuff and is used by the U. S. Navy.

My next stop was Lowe’s for a foam brush.  I picked up a 4-foot length of angle, four U-bolts, two pulleys, some miscellaneous nuts and bolts, and a 100 foot length of 3/8″ polypropylene rope, all of which was in preparation for ham radio projects tomorrow on the small tower.  After Lowe’s I stopped across the street at O’Reilly’s Auto Parts store to dispose of the oil and filters.  Their parking lot was being seal-coated and I could not get to the disposal bins so I will have to try again tomorrow.

By the time I got home it was 4:30 PM.  Rather than start working on the bus I did a little more trimming on the trees by the road in front of the house and then put the yard tools away.

For dinner Linda made a whole wheat linguini with mushrooms, onions, and sun-dried tomatoes lightly sautéed in EVOO.  We opened the bottle of Frey Natural Red organic/vegan wine.  It was very dry which made it difficult for me judge its other qualities as I do not care for dry wines or wines with noticeable tannins.  Still, it went well with the dish and I finished my glass.  I don’t think I will ever develop a taste, however, for dry wines and/or wines with a lot of tannins.

After dinner I worked on an article for Bus Conversion Magazine (BCM) about our experience on the Habitat for Humanity build we participated in back in July 2013.  The article has been done for a while but the publisher (Gary) had someone (Teresa) proofread it a couple of days ago and she found some minor things that I needed to correct.  Gary and I are also discussing whether to split the article into two parts and/or cut down a bit on the number of photos, which currently number about 60.  I took a break from 8 to 11 PM to watch television with Linda and then returned to working on the article before going to bed.

 

2015/07/16 (R) RV Work

We were up at 6 AM and by 6:25 Mara had started the engine of her motorhome to pull in the slides.  She disconnected the electrical cord and we helped her back out of the driveway at 6:40.  She was pointed west so she had to drive to the end of our street and use the circle to turn around.  Her destination was Cummins Bridgeway in New Hudson.  When she made the appointment they said the closer to 7 AM she could arrive the better.  They estimated she would be there 3 to 4 hours.

Linda did not sleep well last night, a common side effect of eating too much too late in the evening, and went back to bed once Mara was safely on her way.  I decided to stay up and clean the coffee maker before making coffee.

I wiped out the upper housing and cleaned the nooks and crannies with Q-tips.  The upper housing is undoubtedly designed the way it is to make it structurally adequate with a minimum of plastic but it was equally obviously not designed with any consideration for being able to clean it.  Like many things, it leaves me wondering if the designers ever use the products they design or what sort of functional specifications they work from and who develops those.  I think the Bauhaus had it right when they declared “form follows function.”  My guess is that commercial equipment, while less “stylish” than consumer goods, has cleanability and serviceability as primary design considerations.

I remembered that we had a one gallon jug of distilled white vinegar in the bus so I got that and ran eight cups of it through the coffee maker.  I added four cups of water to the used vinegar and ran it through again.  I then ran 12 cups of RO water through the coffee maker.  By the time I was done it was approaching 8 AM so I ground up some of the Sumatra Mandheling beans (not decaffeinated) and made seven cups of coffee.  I normally make 8 – 9 cups but this was full-strength stuff.  I’ve been making 11 cups while Mara is here but it turns out that she does not drink much coffee so I will be back to my usual 8 – 9 half-caff servings going forward.

I enjoyed my first cup of coffee while finishing yesterday’s blog post and starting this one.  I enjoyed my second cup while researching hardware for mounting a small table to a wall so that it is essentially cantilevered, which is the table arrangement we need for the bus.  I found a 2-piece aluminum extrusion that might be the solution for attaching the table to the wall.  It is 30″ long and can be cut to length but I do not think it will not be strong enough by itself to support the table.  I found an angle bracket on Rockler that might be the additional piece I need.  It is 12″ x 18″ with a notched corner, made of 1/8″ steel, and powder-coated black.  A pair of them will support 1,000 pounds so one in the center would be more than sufficient.  An alternative would be a wood strut angling back to the wall but we are not willing to have a vertical table leg.  I have not decided whether the table should be removable but I am leaning towards a more permanent installation.

Linda eventually got up but neither of us were hungry so we did not have breakfast.  I went to my office and ordered the ZioTek monitor mounting system from CyberGuys.  I then e-mailed Ewa at AFC Industries and thanked her for the second quote but let her know that the price was way out of my budget.  I finally settled in to work on the custom desk design for the bus and eventually finished it (I think).  Linda left around 12:30 PM for her dermatology appointment.

Now that we have base station antennas cabled to the ham shack I tend to have the new Yaesu FTM-400DR/DE dual band (VHF/UHF) radio on whenever I am working in my office.  It provides a pleasant diversion from my other tasks and is actually useful.  Somewhere mixed in with everything else were a couple of QSOs with ham buddies and an attempt to coordinate with Steve (N8AR) and Mike (W8XH) about testing my two Morgan lightning arrestors at Steve’s QTH.

Our bus had settled in the rear and was clearly out of level.  The reason it had settled was that I forgot to switch the suspension system to Level Low and shut off the air to the engine accessories.  It was of no consequence but it bugged me so I started it, let it air up, re-leveled it, shut it down, and switched off the batteries and engine air accessories.

Mara returned from Cummins Bridgeway around 1 PM and I guided her back into her parking spot.  They did the routine service on her motorhome engine and generator but found several things on the genset that needed to be repaired.  She agreed to have the work done so they removed the genset from her rig and will reinstall it next Wednesday.  They also inspected the motorhome and gave her a list of other things that needed to be fixed, some right away and some eventually.  She did not have them do any of that work as she wanted me to look at the list first.  The added service work means Mara will be visiting with us for at least another week, which pleased us greatly.

I went over the list with her and we discussed the relative importance and urgency of each repair.  One of the items involved the caulking on the roof so we both climbed up there to have a look.  I also wanted to scope out how we might install her weBoost Drive 4G-X cellular booster system.  While we were on the roof I was able to rock the rig side-to-side quite a bit just by shifting my weight.  One of the other items on the diagnostic list was shock absorbers and I indicated that I thought that sounded appropriate, especially given that the back ones reportedly had cracked/broken mounts.  They also noted that the transmission fluid was low and that the filter and fluid should be replaced.  I encouraged her to have these taken care before she left as Cummins Bridgeway is a very good service facility.

The other items were things that could wait but the caulking of the roof was something Mara could do herself.  She likes to take care of as much of her rig as possible and she will be here through at least Wednesday, so she has time.

Linda got back from her out-patient surgical appointment with bandages in seven different places.  We visited for a while and then I left the ladies and returned to my office.  I started on the design of the pull-out pantry for the bus and quickly realized that the very expensive Fulterer heavy-duty pull-out pantry slide I ordered from Rockler was too wide for the space we have available.  I came upstairs and groused about it for a while until Linda and Mara urged me to try canceling the order.  I called Rockler and spoke to someone in customer service.  I won’t know until tomorrow at the earliest, and probably not until Monday, if I was successful in intercepting the order before it shipped.  If not I will have to pay to ship it back and may have to pay a restocking fee.  Although I do not have anywhere else I can use it at the moment, between the restocking charge and the cost of shipping I may just keep it and find a use for it.

Linda made a large salad for dinner and we chatted during and after the meal.  It had been an early, long, hard day for all of us.  Mara returned to her rig before it was dark and Linda headed off to bed shortly thereafter with me not far behind.

 

2015/07/15 (W) Prime Wednesday

It was brisk when we got up this morning, with the temperature in the upper 40’s (F), light breezes, lower humidity, and clear, blue skies.  When the weather in Michigan is at its best it is near perfect.

After our usual coffee and granola we spent a little time browsing Amazon.com looking at their “Prime Wednesday” sale.  Neither of us are compulsive shoppers or impulse buyers and scrolling through thousands of items on a slow Internet connection looking for something we can’t live without at a price we can’t pass up is not our idea of fun.  I have things I need to order, like the multiple monitor mounting system for the ham shack, but it quickly became obvious that I was not going to find those items for sale as part of Amazon’s special July 15 Prime Sale.

Mara was up and took her garbage to our trash to can and returned to her rig.  Linda then took our garbage out and moved the can to the street.  By 10:30 AM Mara had not yet emerged from her rig, so I went to my basement office and resumed work on the custom desk design for our bus.  I still need to design the pull-out pantry but I finally ordered the Fulterer top/bottom slide mount from Rockler and had it shipped directly to Jarel in Logansport, Indiana.  It is a serious piece of hardware that will support 450 pounds, so it should be more than adequate for the task.

Mara eventually emerged from her rig and the ladies left for 12 Oaks Mall and Mara’s first ever appointment with Renee in the J. C. Penney’s Salon.  They were gone quite a while, tacking on several stops at pet and food stores before returning home.

I received a second quote for a wall-mounted monitor mounting system from AFC Industries.  It included itemized pricing and an offer of a 15% discount but was still way too expensive.  Though more expensive than a desk-mounted pole system I decided I to order the ZioTek wall-mounted monitor mounting system from CyberGuys.  Being wall-mounted it will get my monitors completely off the desks, leaving room for ham radio equipment to slide underneath and all the way to the back edge of the desk (and beyond).  It will also isolate the monitors from the desk so they won’t move if the desks are bumped.  Another bonus is that I can move the desks to get to the cables at the back of the radios without having to move the monitors.

The monitor mounting system is a significant purchase so I wanted to make sure the components would work the way I need them to.  I measured the three monitors that will initially be mounted using the system and then made a scale drawing to see how they would fit.  I added all of the items to the shopping cart and was getting ready to complete the purchase when I noticed that a 5% discount was available if I joined their e-mail club.  I signed up, received an e-mail, and confirmed my intention to join but the 5% discount did not show up in my shopping cart.  I called the 800 number and was told it would take 24 hours for the discount to be available so I cleared all of the items out of the cart and will re-enter them tomorrow.

I finally settled in to my design work but took several breaks to talk to friends on the Novi and South Lyon repeaters.  The Morgan Manufacturing VHF/UHF lightning arrestor was once again degrading my signal to an unusable level/quality so I once again disconnected the antenna and radio coax and joined them together with an N-female to N-female barrel adapter.  Once I did that I was able to transmit and receive to/from both repeaters full-quieting.

I exchanged a couple of e-mail updates with Jarel Beatty, the cabinet maker in Logansport, and finally quit working around 5 PM.  I came upstairs and found that the weBoost cellular booster systems had arrived from Amazon so I unpacked the shipping box and opened them.  I had not realized when we ordered them that they were designed for use in a car with an inside antenna that requires the phone or other cellular device to be 18 – 36 inches away.  That is not very far and it is a fairly small range.  As the name implies, however, it is designed for use while in motion which is what both we and Mara need/want.  I decided to temporarily install one of them in Linda’s car to test it.

Sitting in the driveway in a relatively bad location my phone was in 3G mode with a weak, but usable, signal that hovered around -115 to -118 dBm.  With the booster turned on my phone switched to 4G-LTE and the signal strength improved to anywhere between -103 to -94 dBm.  (The less negative the signal strength in dBm the stronger the signal.)  That may not appear impressive on the surface, and it was certainly not the 50 dBm gain that is claimed for this device, but it was actually a significant improvement.

“dB” is the abbreviation for “decibels” which is a logarithmic scale.  Logarithmic scales are useful for representing quantities that vary over a large range, like cellular signal strengths.  A change of 3 dB represents a factor of two, i.e., a doubling or halving of the quantity.  Thus a change from -118 dBm to -115 dBm (decibels to a millivolt) represents a doubling of the received power.  It is still a weak signal, but it is twice as strong.  Going from -118 to -103 is a change of +15 dBm and is five doublings (-118 to -115 to -112 to -109 to -106 to -103) which is an increase of 2x2x2x2x2 = 32 times.  Continuing from -103 to -94 is another +9 dB change representing three more doublings (-103 to -100 to -97 to -94) for a total gain of 32x2x2x2 = 32×8 = 256 times.  Starting from a signal in the -118 to -127 dBm range that is potentially the difference between useable and not useable.  (BTW:  a change of 10 dB is a factor of 10, so going from -115 dBm to -105 dBm and then to -95 dBm represents an increase of 100 times.)

We had decided at dinner last night that we wanted to go to The Blue Nile restaurant while Mara was here.  The best time to go turned out to be this evening, so Linda made an online reservation for 7:30 PM at the Ann Arbor location (there is also one in Ferndale).  We tested the weBoost Drive 4G-X cellular booster on the drive to/from Ann Arbor and it definitely made a difference in the signal strength we saw on our phones.

It wasn’t until we got part way down Main Street that we realized that today was the opening day of the Ann Arbor Art Fair.  The last place I wanted to be driving, parking, or walking was at the Ann Arbor Art Fair, not because I dislike art (we love art), and not because I dislike art fairs, but because I dislike congested traffic and crowds, which the AAAF has in abundance.  Surprisingly, we were able to park in one of the parking structures a couple of blocks from the restaurant.  After fighting our way through the pedestrian traffic I was even more surprised to find the restaurant essentially empty.  The Blue Nile is slightly outside the portion of Main Street where the AAAF takes place and streets to either side that are closed off to vehicles during the AAAF.  All of the restaurants and the beer/burger joints in and around the AAAF venue were doing a brisk business, especially if they had outside seating (it was a very pleasant evening), but the restaurant was open and the host was very gracious.

The Blue Nile serves Ethiopian cuisine.  Some of the tables are upside down rope baskets with four chairs and two side tables.  We always ask to be seated at one of these because we always order the Vegetarian Feast which is, in fact, vegan.  The Feast comes on a large round tray covered with a layer of Ethiopian sponge bread (made from teff flour) with small piles of the seven different vegetable-based dishes on the menu surrounding a pile of (optional) salad in the center.  Beverages and platters of rolled up sponge bread are placed on the two side tables (we had water and Ethiopian spiced tea).  The meal is eaten by tearing off suitable sized pieces of sponge bread and picking up the eight different selections from the tray.  Before the food was brought to the table we were given hot, moist towels to wash our hands.  Nice touch.

The food was amazing and the experience somewhat more communal than sitting at a standard American table and eating with utensils.  The waitstaff was gracious and attentive and it was a wonderful experience for all three of us.  Mara asked one of the waitstaff to take a picture of the three of us, which they gladly did.  She then uploaded it to her Facebook page along with a brief description of her visit and meal.  One the drive home she already had 12 “likes.”  This is the side of Facebook, and other social media, that is fun.

It was getting dark by the time we got back to the house but we took the time to unload Mara’s kayak from its special mount on the rear of her motorhome that is installed in the tow receiver.  The kayak mounts diagonally from the lower driver side up past the roof on the passenger side and the tip is about 13′ 2″ above the ground.  She was leaving at 6:30 AM the next morning to drive to Cummins Bridgeway to have her main engine and genset serviced and would be traveling south on Hacker Road to Grand River Avenue.  The last time we did this we clipped a branch in the southbound lane on Hacker just north of Bendix Drive not far from Grand River Avenue.  I was concerned that she would catch the same branch and damage her kayak which is why we took it off the rig.

Once the kayak was off the back of her rig and sitting in our yard we said a quick “good night” and all trundled off to bed as 6 AM would come all too soon.  I wrote for a while in bed but was too tired, and full of food, to stay awake.
